KRC-5 Micro Outputs on XG12 interface Board Standard aren't showing 24v?

    Hello, I'm quite new to KUKA robots and I'm trying to get the Digital Outputs to work so i can turn on some Lights on the end of my robot ( KR6 R700-2) but for some reason the 40 pin connector on the end of my KRC-5 Micro isn't showing 24v on my Multi Meter.

    I believe i have the Outputs mapped Properly and i have 24v going to XD12. even after i update the project using Work visual it doesn't seem to work. do i need to configure anything else prior to trying the Outputs? from what I've seen on this forum and google i cant find anything that can help.

    i have looked at the manuals and it doesnt seem to show anything in relation to this problem so any help would be great.

    Approved the thread.

    how exactly did you connect 24VDC to XD12?
    how exactly you are measuring ?
    how exactly are IO configured?
    how exactly you are trying to set the outputs and are you succeeding? NOTE: setting outputs through HMI requires drive enable.


    to use IO on KRC5 you need to read relevant documentation and:

    bring 24VDC power to XD12, positive need to go to terminal on the right. Traditionally KUKA used to bring power to first connector terminal. But with KRC5 KUKA broke with that tradition, so here positive terminals are 2 and/or 4.

    wire XG12 (bring the IOs to terminals). if you are using them as NPN type, you also need to insert jumpers at relevant terminals:

    for outputs 1-8 to be NPN, connect 5 and 6.
    for outputs 9-16 to work as NPN, connect 7 and 8.

    if using them as PNP leave those terminals open.

    If they are setup as PNP outputs, you need to measure relative to 0VDC of your supply. Set DMM to measure voltage, connect black probe (COM) to negative rail of your 24VDC supply, use use red probe (V) to test outputs.

    But if they are setup as NPN, you need to measure relative to positive rail. Set your DMM to voltage, connect red DMM probe to positive terminal of your 24VDC supply, use black probe (COM) to test outputs.

    map IO in WorkVisual

    deploy and activate WorkVisual project

    use I/O and see the change...

    1) read pinned topic: READ FIRST...

    2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly

    3) read 1 and 2

    Hi Panic mode, i got the I/Os working. it was a combination of user error and the KRC-5 Micro was 5 mins ahead on its clock so it wouldnt let me upload the code.

    thanks for your help it was much appreciated

    yes of course.

    I had the 24v from a 24v power supply plugged into XD12 +24v in 4 and GND in 3

    I had to download the Profinet 6.0.KOP File from the KRC-5 Micro and install the option into WoV to remove a COMM's Error I was receiving.

    i then mapped The I/Os' to the ones on the Interface Board - Standard that I wanted to use.

    After i had them mapped as I required I was resetting the active controller and and clicking update instead of Deploy Project , which I believe is where I kept going wrong.

    before i could deploy the project I had to change the time on my KRC-5 Micro to the same date and time as my laptop as well as set the time zone correct to allow me to deploy the mapping to my Controller.

    once the time update was sorted I deployed the Project and set the Output manually on the pendent and it turned on the Relay I had wired up.

    after I did everything above it worked perfectly. I hope this helps anyone with a similar issue in the future. :smiling_face:
